A 3D curved structure and LED 3D curved lead frame for a curved surface illumination of an illumination device. First of all, draw illumination circuit with banded structure of multilayer lead frame on 3D illumination curved surface, then spread these curved circuit into plane circuit, dismantle the banded structure of multilayer lead frame of circuit into circuit pattern of single layers, use process the prototype of circuit patterns of each layer with conductive metal charge tape, and produce the prototype of banded structure of multilayer conductive frame through repeated accumulation of multi-disc charge tapes, and install the LED chip on the installation seat to get LED flat lead frame, then flex the conductive metal into LED 3D curved lead frame with jig and paste on the luminous curved surface, and package them with transparent material.

LED 3D curved lead frame of illumination device

This invention relates to separately produce the complicated 3D curved structure and LED 3D curved lead frame to meet the demand of the complicated curved surface illumination of illumination device. First of all, draw illumination circuit with banded structure of multilayer lead frame on 3D illumination complicated curved surface, then spread these curved circuit into plane circuit, dismantle the banded structure of multilayer lead frame of circuit into circuit pattern of single layers, use process the prototype of circuit patterns of each layer with conductive metal charge tape, and produce the prototype of banded structure of multilayer conductive frame through repeated accumulation of multi-disc charge tapes, and install the LED chip on the installation seat to get LED flat lead frame, then flex the conductive metal into LED 3D curved lead frame with jig and paste on the luminous curved surface, and package them together with transparent material, for example, curved decorative lighting, spherical display advertising board, etc.; this method offers more flexibility for structure and aesthetic design, and fully utilizes the high heat dissipation capacity of main body of metal part.

An integrated illumination part is produced by installing annular lead frame with luminous LED chip on main part body of the umbrella, then packaged into one unity with transparent material such as plastic or silica gel, slip ring, installation seat, handle and other parts can be used to produce the part. The structure of annular lead frame made of sheet metal whereby to increase the mass production of integrated illumination part and diversity of light source. It thus fully utilizes high heat dissipation capacity of umbrella parts. It includes single-layer and multilayer structure according to the functional demand of LED chip; the manufacturing method of annular lead frame firstly produces LED chip and lead frame into LED lead frame, then bend it into annular with jig according to the appearance of main part body and fix power pin into annular structure with fastener.

Integrated illumination part and lead frame of umbrella

The manufacturing method of the integrated illumination part used in the present invention is to install annular lead frame with luminous LED chip on main part body of the umbrella, then package into one unity with transparent material such as plastic or silica gel, for example, slip ring, installation seat, handle and other parts can be used to produce the part. The purpose of the present aims at innovating the structure of annular lead frame made of sheet metal whereby to increase the mass production of integrated illumination part and diversity of light source, and fully to utilize high heat dissipation capacity of umbrella parts. It includes single-layer and multilayer structure according to the functional demand of LED chip; the manufacturing method of annular lead frame is first to produce LED chip and lead frame into LED lead frame, then bend it into annular with jig according to the appearance of main part body and fix power pin into annular structure with fastener.

The present invention relates to an improvement in the structure of luminous umbrella, using integrated illumination components. The components are ideal for luminous umbrella particularly designed to be used in the evening when visibility is poor, and can be used for other decoration purposes. The integrated illumination components of the present invention are constructed by combining illumination emitter of LED with bases of parts of umbrella, such as linkage members on slip ring, rib members on fixed collar and umbrella handle. When the illumination emitter of LED is mounted on the surface of these parts, the overall umbrella structure can be made smaller and lighter, and the flexibility of light source design can also be maximized. In particular, when base parts with high heat dissipation capability are used as the heat dissipating fins, the full performance of high-brightness illumination emitter of LED can be achieved. The integrated illumination components offer another advantage. With the flexibility of design in the number of illumination emitter of LED and the angle of light projection, the components allow light to be fully projected onto the semi-transparent canopy, which turns luminous umbrella into a lantern with both illumination and warning functions when used at night. Umbrella users thus become obvious objects when walking at night. If color illumination emitter of LED is used, dazzling colored lighting design can be created to the satisfaction of both designers and users, achieving the decorative and aesthetic effect.
